r.mapcalc generates raster map with two values - 1 for areas where slope
is greater then 30% and 0 for areas where slope is lower or equal then
30%.
Martin,
Is the reverse 'slope_30 = if(slope_map < 30, 1, 0)' mean that areas = 1
are < than 30% and areas with 0 are >= 30%?
My question is the value of areas where slope = 30% are placed with the
different mapcalc expressions.
Thanks,
Rich
